skppy.parser_legacy.envelope¶

Parse the legacy file envelope and its authoritative class-version map.

The envelope precedes the root object graph and records product/version text, the model GUID, an informational saved path, timestamp, and CVersionMap. Later readers select every class layout from the returned ArchiveSchema; they never infer a layout from neighboring bytes. Use skppy.load() for normal model loading.
